Answer: A
Explaination:
The cause and effect relationship of a certain phenomenon under controlled condition
Answer:
The factors of
is ((x+y)-5)(2x+2y+1)
Step-by-step explanation:
Given polynomial
=>
To Find:
The factors of the polynomial =?
Solution:
Lets assume k = (x+y)
Then
can be written as 
Now by using quadratic formula
k =
where
a= 2
b= -9
c= -5
Substituting the values, we get
k =
k =
k =
k =
k =
k= 
k =
k =


Solving the RHS we get


Substituting k = x+y


A) (-2)² ≠ -4 is your answer
Explanation:
(-2)² = (-2)(-2)
(-2) x (-2) = 4
∴ A) (-2)² ≠ -4
hope this helps
